LinuxWorld Expo 2007 Keynotes I attended

|

I attended two of the keynotes at LinuxWorld Expo 2007 and here they are as nicely recorded by the LinuxWorld folks. If only these videos were downloadable.

I put the second one on the full story page. It is a talk by one of the founders of VMware about the future of virtualization technologies.

Screencast: OpenVZ Live Migration

| |

I just recently started playing around with installing desktop environments inside of a VPS. It takes a little work as you really don't want to accidentally replace your vzdev package with a distro's stock udev package. Anyway, the video below was resized for embedded flash playback and there is no sound. If you want a MUCH higher quality video, you can can right-click and save as: openvz-via-vnc-with-migration.ogg.

Read the full article for the embedded video because I didn't want it to stretch out the front page.

LinuxWorld Expo 2007 Video footage

| |

I took my video camera hoping to do some interviews but given the fact that my first experience using it led to a visit from security telling me I couldn't record anything but the booth I was in... I was a bit wary about recording after that.

Along came a guy (although I didn't catch his name) doing what he called, "50 second .org videos". I latched onto that... and filmed him filming several of the .org booths.

Enjoy if you can a mish-mash of 36 minutes worth video clips. You'll see the following booths: Fedora, OpenVZ, Joomla, The Linux Foundation, Pentaho, and Ubuntu... although technically the Ubuntu booth was not in the .org Pavilion.

I got Carla's permission (from SWsoft) to film the presentation she did on Virtuozzo at the Intel booth... but she let me know up front that it was geared more towards how Intel and SWsoft work together rather than a general presentation on Virtuozzo. That part is about 10 minutes and it isn't too bad.

In the mean time...

Ok, I fed my video from LinuxWorld Expo 2007 into a computer and am processing it now but in the mean time I found this interesting video from Geek Entertainment Television that should tide you over.

LinuxWorld Expo 2007 Day 1

|

Got to the booth at 9 AM. Got the laptops setup. Set out the DVDs. Kir had some flyers he had printed at Kinkos... and the banner was hung nicely.

All five of us were there in the booth today so we all got a chance to take turns talking to people. The booth had quite a bit of activity. We gave away all 25 DVDs we had burned within the first few hours so Kostya and Warren were busy burning DVDs on both of their laptops for most of the day to keep up with demand.

The basic question everyone asked was... how is OpenVZ different from VMware... or Xen? I got rather good at explaining OpenVZ's seven main points.


LinuxWorld Expo 2007 Day Zero

| |

Front DoorFront DoorToday is Tuesday and the show started today BUT I haven't written about Monday yet so this is about Monday.

Decided to go the Moscone Center around 11 AM. Checked in at the exhibitor desk and got an exibitor pass. While we were walking around trying to find the OpenVZ booth I had my video camera out and was taping the journey. Warren was taking pictures with his digital camera. The exhibitor floor was chaotic. There were dozens of fork lifts and various other vehicles running around. Many of the exhibitors have very elaborate booths that take a long time to setup. Finally found the ".org Pavilion" which is just a section of booths in the fair right corner of the exhibit floor. Most .org exhibitors just have a table, two chairs and perhaps a banner. More pictures in full article.


Linux Telephony: Not so short Overview

For those interested in telephony on Linux, I ran across this engEDU video on Google Video this morning.

Getting ready for LinuxWorld Expo 2007

|

Next Saturday (August 4th), Warren and I head off to San Francisco for the LinuxWorld Expo 2007. We will be helping to staff the OpenVZ booth at the .org Pavilion.

This opportunity kind of fell unexpectedly into my lap when Kir posted an announcement that they were looking for a few community members to help staff the booth given the fact that they had seven exhibit passes and would only be sending two of the OpenVZ developers over from Russia, "as to not stall development."

I've been increasing my OpenVZ knowledge and plan to practice giving demos with Warren a bit on Sunday and Monday. I've been using OpenVZ on a daily basis for over a year now, given two public OpenVZ presentations, written several articles... so interacting with community members and promoting OpenVZ to the crowd at LinuxWorld Expo seems like a natural progression. I really look forward to meeting Kir Kolyshkin and Konstantin Khorenko from the project as well as Marc Perkel who will also be staffing the booth.


libvirt begins to add OpenVZ support

| | | |

I noticed a blog posting by Daniel Veillard on Fedora People about initial support for OpenVZ being added to libvirt. If you aren't familiar with libvirt, it is an underlying library/API that can be used by higher level tools to create, manage, and monitor virtual machines. libvirt is trying to be technology agnostic by supporting several virtualization technologies. They started off with Xen and QEMU but have since added KVM. libvirt is used by the GUI tool Virtual Machine Manager which first appeared in Fedora Core (now Fedora) but became part of Red Hat Enterprise Linux 5.

Looking at some of the postings in the libvirt mailing list archive for this month, it is mentioned that adding OpenVZ support is a bit different than previous technologies because the OpenVZ tools are already GPLed, "simple and straight forward", and than OpenVZ additions to libvirt "ends up looking very close to the original". I don't know how far away complete support for OpenVZ is in libvirt nor when it will show up in Virtual Machine Manager but I definitely look forward to it... although I doubt it would completely replace vzctl and the other OpenVZ tools for me.


My first Rocks Cluster

Rocks ClusterRocks ClusterI finally got Rocks Cluster installed today. I installed it on the six dual Xeon/P4 machines that Intel donated. Getting this going has taken me a lot longer than I had hoped. It wasn't the fault of the Rocks Cluster software package but the odd combination of hardware.
